Sounds like the same symptom I got in an '83, which turned out to be 
a stuck thermostat not opening enough (or at all). Could also be air 
caught in the system somewhere. 
Check the temperature of the hoses at the front - if they're only 
warm, then its the thermostat. I'd replace the thermostat & bleed 
the system first. Then check that the fan switch will come on after 
prolonged idle. If not, replace the fan switch.
